l mechanism is constituted. by two flexible 'olates A and A carrying at i uo'oer iitr mitv the feed fin 'crs B J .i V eb olates are at their lower part to an eeclingly light slitle block C whicl mores upon rod D forming an integral part oiithe frame of the apparatus. The plates A and A are stayed at the upper h a member G comprising a protuherwhich is adapted to slide upon a c red I forming part a rigid trams a frame itself is pivoted upon .gral with two hearings L L "c frame-work of the apparatus. of the frame is connected at M l rod N which through pport U while its other end 0 i. cam slot or groove P rigid R and with the shutter S. of relation is imparted to the inilii'ifilllal'y of four bevel I T of which the latter is crank disk by the intermeiiato E- transmits a vertical reocuiiiig movement to the slide block C the pitman is pivoted at F.

As the crank plate "V continues its movement, the asseinhia 'c constituted by the slide block, the plates and A and she fingers B and B, will rune an iqawaiw'" movement and when the Whole occupies the u por position, the cam, P which has cor tinned its own movement of rotation, 4 press hack the rod 'N, which in its turn xvi 2 act upon the frame i, J, I, J, and will permit the flexible plates A, A" to again cause their fingers'B and B to enter the perforations in the filn, and so on in succession. 'Ilowarcl the end of the down stroke the slide block C compresses the spring E which serves always to limit in ihe same directioni he play that the pier iaii E able to client upon the iii'unuiou The special feature oi? this zhe haijiism is that he feed fingers always occupy Li, H the same position at the lowe that to say as the moment at which 1 i 11" effort upon the him ceases and this still oh tains even after the apparatus has been in use considerable iinie, owing to ihe eiinih nation of the pic-by which is always sci between mechanical elements :ic-h are relanivcly clisplaceablc.

'What is claimed is l. Mechanism for intermittently feeding a film in kineiiiatographic'apparatus, comprisinga. slide block, a yilimau and a. cram for reciprocating said slide block, said block carrying flezgible plates provided wish feed fingers, and means for i'exing saidii'ieifll ie plates for witliclrawin said fingers from iilm at an appropriate time merit of said slide block.

2. Mcchaiiism for intermitieiitly feeding for reciprocating said slide block said block carrying flexible plates provided with feed fingers, an oscillating frame having :1 sliding connection. with Lili flexible plates, and means for oscillating said. frame "for flexing said flexible plates for Withdrawing; said fingers from the film at an appropriate time in the movement of said slide block.

3, Mechanism for intermittently feeding: a film in kinemetogmpliic zi 'ngarelus, comprising a slide block, piiinan and ii crank for reciprocating said slide block, seiil block carrying flexible plates provided with ieetl fingers, a pivoted osciilatory frame, a rod therein slidingly engaging said flexible plates, and means for oscillating said frame for flexing said plates to Withdrmv said fingers from the film at an appropriate time in the movement of said guide block.

4. Mechanism for interinittentiy feeding 2L film in kincinatogrziphic apparatus, comprising a slide block, a pitnion and EL crank for reciprocating said slide lolocli said block carrying flexible pistes provideli'with feed fingers, and means for flexing seiii flexible plates foc'withclrawing snicl fingers from the lilni at an appropriate time in the movement of said siiale block, said slide block having :1 spring in its path Which adapted to be compressed at the end of the clown stroke of snicl block for limiting in one direction the play which may arise in the operating members.

In Witness whereof, I have hereunto signed my name in the presence of two sub-- scribing Witnesses.
